Re: Lot of dots on the screem
I'm not familar with that brand, but would check for bad solder connections by tapping the side of the set while it was on to see if the dots would come and go. If that has no effect, then it may be cheaper to replace it.

Yes. Sounds like the power supply is shot. However that being said do not be suprised if after changing the power supply you find that the main board is gone out as well. Take the cost of that board as well into consideration before repairing. My insignia did the same thing and parts alone were more than the set was new...fortunately mine was under warranty.
If its four years old that is about the average lifespan of one of these sets; a guess would be either voltages drifting or off in power supply or one of the signal boards that processes information is going bad.
The tv dam light engine block it is the causes an the problems.This a major design flaw in the tv light engine block by the tv Corporations Samsung,Mitsubishi have this problems more than the other big screen tvs brands.A brand new tv?Take ur warrenty repair quickly,this things wouldn't stops.The white and black dots will continue and keep comming more and more.Until the tv have replace the light engine block or have it replaced another cuircuit board that help the light engine block too work.
Hi, I replied your previous question, click HERE to read it again. If tv shows bright picture in proper focus then it would last few more years as it is rear projection tv that has 3 picture tubes (red-green-blue) to project color picture on front screen. Its your choice to have new tv instead of repairing this one and yes, its correct that 32 inch tv is available under 700-800 dollars. Hope these info will help you. Thanks.
This problem cause by DMD chip has been defective. This chip consist of over 2 mil mirrors tiltling to make picture. Some of the mirror does not function causing white dots. If you are in Cali, Orange, Sandiego or near by. Email me at: email@example.com so I can come and help you. This replacement need skilled technician to relace as it was inside the DMD board.
Sounds like your panel is on its last legs so to speak.
Might be time to look into replacing the panel. Running a high contrast can lead to a shorter panel life which may cause the occurence of dead pixels.
Hello - it's called burn-in and is a common problem with Plasma TVs. It happens around the 3 year mark. Later models from Hitachi have a white-wash option which can wipe the screen free from blurred marks etc. Have a look in your manual to see if this feature is available in your TV. If not, and you have a video camera, you can replicate the effect by filming a white sky or something similarly bright and white, then playing it through your TV and pausing the plainest, whitest shot you have. You'll need to keep this showing for around 24 hours. It's important that it is completely white, as if any of the film has a dark dot or mark, this will add to your burn-in problem. It's a bit of a long work-around, but it does work. Bear in mind that as your screen ages the problem will return at some stage. LCD displays don't suffer from this problem so that's something to bear in mind when the time comes to replace your TV. I hope that helps :o)
